• the physical host is HP 380p.
• the virtual machines are 1. windows server 2019 2. win 11 pro 3. debian 12 XOA.
• on each of these three virtual machines I share a folder for testing. Each of these machines is an SMB server - not a client.
• the client is my work computer which is in the same LAN. But according to the LAN infrastructure issue does not matter.

Hello. I have a big problem with Windows server 2019 performance. We have a program with databases in files that is shared via SMB. And while reading is about 100 MB/s, writing is only 30 MB/s. Host is HP 380P, 2x SSD Raid 1 + 2x SAS Raid 1. Windows server 2019 is on SSD drives, for testing I installed Win 11 on SAS drives and the same performance - 100/30 MB/s. For testing I ran Samba on Debian 12 XOA and the speed is 100/100 MB/s. So generally there is a problem with Windows.

Guest Tools installed - although with problems. I don't know what I'm doing wrong, but the first time I install them I get an installation error. I restart VW and use MicrosoftProgram_Install_and_Uninstall.meta.diagcab to remove XCP Quest Tools, manually in - Device Manager I remove all entries (also hidden ones) containing "XCP ....." and reinstall XCP NG quest Tools. But there is still something wrong. Now I even look and I can't suspect RAM usage in XCP center or XOA because Guest tools must be installed to display stats.

Additionally, during the scan Eset CPU= 100%.

@peder Thanks, it works

what am I doing wrong? Debian 12, XOA from sources.

The recover-account-cli.mjs file is located in the opt/xo/xo-server/dist folder and I still get the error at the end:
